Balance the following reaction

**Balance the following reaction**

\[ \text{[ Select ]} \quad \text{H}_3\text{PO}_4 \quad + \quad \text{[ Select ]} \quad \text{CaCO}_3 \quad \rightarrow \]  
\[ \text{[ Select ]} \quad \text{Ca}_3\text{(PO}_4)_2 \quad + \quad \text{[ Select ]} \quad \text{H}_2\text{O} \quad + \]  
\[ \text{[ Select ]} \quad \text{CO}_2 \]  

**Instructions:**
In the above reaction, you are prompted to balance the chemical equation. There are several dropdown menus labeled "Select" where you need to choose the appropriate coefficients for each compound to ensure that both sides of the equation have the same total number of atoms for each element.

The unbalanced reaction involves the reactants Phosphoric Acid (H₃PO₄) and Calcium Carbonate (CaCO₃), which react together to form the products Calcium Phosphate (Ca₃(PO₄)₂), Water (H₂O), and Carbon Dioxide (CO₂).

**Balancing Tips:**
1. Balance the metals first.
2. Next, balance the non-metal atoms.
3. Balance the hydrogen atoms.
4. Balance the oxygen atoms.
5. Ensure the same number of each type of atom appears on both sides of the reaction.

**Example Solution Strategy:**
1. List out the number of atoms for each element on both sides.
2. Adjust the coefficients in the dropdown menus sequentially to balance one element at a time.
3. Iteratively check and adjust until all elements are balanced.

Remember: According to the Law of Conservation of Mass, the mass and number of atoms for each element must be the same on both sides of the chemical equation.

**Balancing Chemical Equations: Practice Problem**

**Objective:** Balance the following chemical reaction.

**Unbalanced Reaction:**

\[ \text{H}_3\text{PO}_4 + \text{CaCO}_3 \rightarrow \text{Ca}_3(\text{PO}_4)_2 + \text{H}_2\text{O} + \text{CO}_2 \]

**Instructions:**
Use the drop-down menus to select the correct stoichiometric coefficients to balance each part of the chemical equation.

**Drop-down Menus:**
- The reaction has three [Select] fields on the reactants side next to \(\text{H}_3\text{PO}_4\), \(\text{CaCO}_3\), and the empty space beneath it.
- Similarly, there are three [Select] fields on the products side next to \(\text{Ca}_3(\text{PO}_4)_2\), \(\text{H}_2\text{O}\), and \(\text{CO}_2\).
- Each [Select] drop-down menu allows you to choose a number from 1 to 5.

**Example Choices for Coefficients:**

When you click on any drop-down menu, you will see the following options:
\[ \text{[ Select ]} \]
\[ \begin{array}{c}
1 \\ 
2 \\ 
3 \\ 
4 \\ 
5 \\ 
\end{array} \]

**How to Balance:**

1. Identify the number of each type of atom on both sides of the equation.
2. Adjust the coefficients in the drop-down menus to ensure the same number of each atom appears on both sides.
3. Ensure the final equation respects the law of conservation of mass.

By engaging with this interactive tool, you will deepen your understanding of stoichiometry and the balancing of chemical reactions.
